Question 600313
13xx+13yy=49.            I need to decide if it is an ellipse, parabola, hyperbola, or a circle. Once I decide I need to put into the right equation and  be able to graph it.
----------------
I think you mean
{{{13x^2 + 13y^2 = 49}}}
{{{x^2 + y^2 = 49/13}}}
A circle, center at the Origin, radius sqrt(49/13)
